    // See Global Unlock Sample for sample code.

    // The bootstrap secret will contain the following information:

    // AWS Region
    // AWS Access Key
    // AWS Secret Key

    // or in the local manager (Windows Credentials Manager or Apple Keychain)

    // Set the location of the bootstrap secret.
    // Can be "local_manager" or "memory", depending on how you setup the bootstrap secret.
    // ---------------------------------------------------------------------------------------------
    // If your operating system is NOT Windows or MacOS/iOS, then change "local_manager" to "memory"
    // You can also, if desired, use "memory" on Windows and MacOS/iOS if your bootstrap secret was previously setup in memory.
